Very cool!
I went to the website listed at the end of the video. "Le Mosquito de Michel Bogaert" Association RRAA - Le Mosquito de Michel Bogaert Association RRAA
It's pretty cool with a lot of pictures of the project. It's all in French, but using an on line translator I was able to find put that the project was started by 3 retired guys and has been going on since 1995 It's taken 30,000 man hours so far. The first flight shown in the video took place only a few days ago. I wish then luck!
